The free distribution of a book doesn't exclude cooperation with a commercial publisher. One does not interfere with the other. As an example, I would like to mention the book Free as in Freedom, which is dedicated to Richard Stallman, the founder of the GNU Project and the free software movement. This book was published by Tim O'Reilly's publishing house under the GNU Free Documentation License 1.1, a license that the author, Sam Williams, insisted upon. Since the license permitted derivative works, the book's central figure, Stallman, released an expanded and revised version several years after its initial publication, which he called Free as in Freedom 2.0. The second edition was published by the Free Software Foundation.
